Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82628, here are decompositions:
- 19 + 82609 = 82628
- 37 + 82591 = 82628
- 61 + 82567 = 82628
- 67 + 82561 = 82628
- 79 + 82549 = 82628
- 97 + 82531 = 82628
- 157 + 82471 = 82628
- 241 + 82387 = 82628
Showing the first eight; more decompositions exist.
